Truss members can have zero internal forces depending on how the loads are applied on the truss. Therefore, identifying these zero force members and eliminating them can simplify truss analysis. There are three main cases where zero force members exist. Case 1: Pin-Pin When members are attached to pin supports AND no applied force is […]

In contrast, when all the forces in a structure cannot be determined directly from equilibrium equations, the structure is considered statically indeterminate. In the latter case, there are more unknown forces than available equilibrium equations, and […]
